Patented Qct. 13, 1931 ARTIUR LONGIR, F ST. JOSEPH, QUEBEC, CANADA EMOUNTABLE VJ'HEEL f Application filed April 25, 1931, Serial No. 532,867, and in Canada July S1, 1930.

The present invention pertains to a novel deinountable Wheel of the general type associated with Ford and other automobiles.

c lThis type of Wheel now in use has ar hub which lits over the brake druin and is held thereto by means of sii: bolts which inust be removed in order to remove the Wheel. The principal object of the present invention is to provide a simple rneans yfor removing the Wheel.

Accordingly the six bolts are dispensed With and are replaced by two eapansible spring hooks carried by the hub and adapted to look in apertures in the brake housing. When it is desired to remove the wheel, these spring` hooks inust be compressed in order to perinit their Withdrawal'through the apertures. rlhis function is accomplished by ineans of pivoted levers mounted Within tie brake and liavini` abut-ments adapted to coinpress the spring` hooks when the levers are moved. The levers are actuated by means et' Canis which havev head portions extending outwardly through the hub and adapted for Only two such cai-ns are necessary and it follows that the wheel may be removed by the adjustment ot two Canis instead ol the reinoval of six bolts as is non7 necessary.

rlhe invention is ullv disclosed by Way of erainple in the following description and in the accompanying drawings in Which y Figui-el is a diainetrical section of a Wheel constructed according to tno invention;

Figure 6 is a similar section showing the Wheel detached from the hub; Figure 7 is plan section View of one of the operating Canis; and

Figure 8 is a detail section of the said cani at right angle of Fig. 3.

Reference to these views will now be made by use of like characters which are employed to lesig'nate corresponding parts throughout. ln Figure l is illustrated au asie l on which i mounted in the usual ina-.nner a brake druni 2 anc. closure plate l rotating` on a suitable )caring e. The wheel comprises a rini and l b joined and spaced by a series of Wire (i. lt will be seen in Fig'. l that the ub 5 lits over one ol' the side plates T of the rali-e heus-ine'. ln order that the hub niay be elfi a l urninzgl relatively to the brake ruin, is formed with a series of lugs 8 'l ch lid into Correspondingly shayried slots 9 formed in 'the plate 7 as may be seen in Figs.

lj 2 and or the purpose of locking the hub to the plate Y, the hub provid-ed on its inner surf vwith inwardly extending wire spring nools l0, each of such hooks being bent over upon itself as at l1. and formed With an angula portion l2 at its free extremity adjacent the hu 'lhese A@ring` hooks are adapted for insertion in slots 13 formed in the plate l "l-he spring hooks when espanded are vfiller than the slots, and the spacine of the angular l2 frein the hub is s as to accommodate the tluclnes of the plate Consequently, after the :rprines have been passed through the slots lli and the nieinbers .j and 7 brought into mutual engagement, the springs expand and overlap the plate 7 outvf'ardly of the slots. thereby locking the hub 5 to the plate 7 clearly illustrated in Fig. 4l. For the purpose of coinpregsing the spring` Ulis lll-l2 to permit deniounting of tl c A. ieel when desireah 'pairs of levers lll are pivoteil 'together at one end and also to the plate 'l' at points l5 clearly illustrated in F igs. 2 and 3. The free ends of the levers are provided vvith opposed lugs or flanges 16. Between these lugs, studs 1? are onrnaled in the plate and are vformed with cain members 18 edneinling into the brake housing and lying between opposed members 1G. The studs are further formed vf' h lzejf heads 19 which pass looselj7 through the hub 5 and are exposed at the outer side thereof for the ouriose which will presently appear.

The levers lll are formed with :itrnck-out tongues 2O lying adiacent and adapted 'lo eugage the inhent portions l'l ol the spring hooks 10. The parts are so related that when the cams 18 are turned to the position shown in F ig. 3 to separate the opposed lugs 16, the members 2O are swung outwardly to compress the spring hooks as showr in 5, wher upon these hooks may be e Aawn through the slots 13, thereby permitting the wheei hub 5 to be detached from the bralre housing,

This action is accomplished by means of a box wrench 2l adapted to engage the heads 19 for turning the same as shown in Fig. 7. it will also be seen that opposed leverfl 14 are normally drawn into engagement with the intermediate cams 18 by means oi connecting springs 22. The arms 1a are held against twisting by means oi studs 23 extendingfrom the plate l into slots 24e formed in the levers. Y 1

Vilhe ordinary wheel or this type is dismounted the removal oi' six bolts, but according to thepresent invention, it is neces- Y saryy to turn only the two heads 19 through an angle ot 900. rilhe apertures inthe hub 5 for accommodating the heads 19 may be two of the six bolt holes provided in the conventional construction. In mounting the wheel on the brake housing, the spring hooks l0-12,

are pushed through the slots i3, and the Cams i8 are adyusted to the position shown in Fig. 2 fo that the spring hoolrs may taire the loch-- ingrposition iiiustrated in Fig. 4i.

although a speciiic embodiment oic the invention has been illustra-ted and described, it will be understood that various alterations in the details ot construction may be made without departing from the scope of the invention as indicated by the appended claims. y

- What I claim is 1. A demountable wheel structure comprising a wheel havinga hub, a body on which saidhub is adapted to it, spring hoolrs carried by said hub and adapted to pass through apertures into said body, said hooks being adapted to expand in said body beyond the margins of said apertures, and means for oompressingsaid hoolrs within said body to Y permit them to be drawn outwardly through `said apertures.

Vfor actuating said levers.

8. A demountable wheel structure com` prising a. wheel having a hub, a body on which said hub is adapted to iit, spring hooks carried by said hub and adapted .to pass through apertures into said body, said hooks being adapted to expand in said bodyibeyond the margins of said apertures, levers pivotally lmounted within said body, abutments carried by saidlevers and adapted to compress said spring hooksto peri lit them to be drawn outwardly through said apertures, cams journal'ed in Vsaid body and engaging said levers, and means exterior ot said lhub for turning' said cams.
